[0002] With the rapid development of society and economy, electric vehicles have been widely used. Before using electric vehicles, they need to be charged, which requires the use of charging piles. The function of charging piles is similar to that of gas pumps in gas stations, which can charge various models of electric vehicles according to different voltage levels.

[0003] Application publication number CN209904575U discloses a vehicle charging device with identification function, including a charging pile, an identification component, and a controller. The controller is operatively connected to the identification component and the charging pile. In use, the vehicle can be charged through the charging pile, and the identification component can identify the vehicle. The device can automatically identify whether the vehicle needs to be charged. However, the device has difficulty clamping and limiting the charging gun, which makes the charging gun easy to fall off.

[0004] Therefore, we are developing an AC charging station with vehicle identification function that can clamp and limit the charging gun to prevent it from falling. Summary of the Invention

[0030] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0031] Example 1

[0032] An AC charging station with vehicle identification function, such as Figure 1 and Figure 2 As shown, the device includes a charging pile body 1, a charging gun 2, a reader 3, a clamping mechanism 4, and a recognition mechanism 5. The charging gun 2 is fixedly connected to the right side of the charging pile body 1 and can charge the vehicle. The reader 3 is slidably connected to the middle of the front part of the charging pile body 1 and can recognize the vehicle's license plate. The charging pile body 1 is provided with a clamping mechanism 4 for clamping the charging gun 2 and a recognition mechanism 5 for moving the reader 3.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the clamping mechanism 4 includes a first guide rod 41, a clamping rod 42, a first spring 43, and a wedge rod 44. The first guide rod 41 is welded to the inner wall of the upper right part of the charging pile body 1. The clamping rod 42 is slidably connected to both the front and rear sides of the first guide rod 41. The clamping rod 42 can clamp and limit the charging gun 2. The first guide rod 41 can guide the charging gun 2. The side of the clamping rod 42 that is far apart from each other is connected to the charging pile body 1 with a first spring 43. The first spring 43 is wound around the first guide rod 41. The first spring 43 can make the clamping rod 42 move and reset. The wedge rod 44 is slidably connected to the upper right part of the charging pile body 1. The wedge rod 44 is in contact with the clamping rod 42. The right part of the wedge rod 44 is made of rubber, which can increase the friction between the wedge rod 44 and people's hands, thereby preventing people's hands from slipping.

[0034] like Figure 2 and Figure 6As shown, the identification mechanism 5 includes a second guide rod 51, a sliding plate 52, a pull rope 53, and a second spring 54. Two second guide rods 51 are welded to the inner wall of the upper right part of the charging pile body 1. The two second guide rods 51 are arranged symmetrically front and back. The sliding plate 52 is slidably connected between the two second guide rods 51. The second guide rods 51 can guide the sliding plate 52. The pull rope 53 is connected to the front right side of the sliding plate 52. The pull rope 53 is slidably connected to the charging pile body 1. The lower end of the pull rope 53 is fixed to the rear side of the identifier 3. The second spring 54 is connected between the rear side of the identifier 3 and the charging pile body 1. The second spring 54 is wound around the charging pile body 1. The second spring 54 can make the identifier 3 move and reset.

[0035] When people need to charge their vehicles, this charging station can be used. Initially, the second spring 54 is compressed. First, people move their vehicles to the front of the charging station, then pull the wedge rod 44 to the right. This causes the clamping rods 42 to move away from each other, compressing the first spring 43. The movement of the clamping rods 42 away from each other releases the charging gun 2, allowing people to remove it. The charging gun 2 separates from the sliding plate 52, which is then released. The identifier 3 moves forward under the action of the second spring 54, allowing for better recognition of the vehicle license plate. The forward movement of the identifier 3 pulls the pull rope 53, stretching it and causing the sliding plate 52 to move to the right. Next, people release the wedge rod 44, causing the clamping rods 42 to move closer together and reset under the action of the first spring 43. This movement pushes the wedge rod 44 to the left and reset. People can then charge their vehicles using the charging gun 2. After charging is complete, people remove the wedge rod 44 from the charging station. The wedge 44 is pulled to the right again, causing the clamping rods 42 to move away from each other. At this time, the first spring 43 is compressed again. Then, the charging gun 2 is reset. Next, the wedge 44 is released, and the clamping rods 42 move closer to each other and reset under the action of the first spring 43. The clamping rods 42 can clamp and limit the charging gun 2. The movement of the clamping rods 42 pushes the wedge 44 to the left to reset. At the same time, the reset of the charging gun 2 will push the slide plate 52 to the left to reset. The movement of the slide plate 52 to the left will cause the pull rope 53 to be pulled again. The pull rope 53 will cause the identifier 3 to move backward to reset. At this time, the second spring 54 is compressed, which can prevent the identifier 3 from being damaged if it is always outside. Repeating the above operation, the vehicle can be charged through the charging gun 2. At the same time, the clamping rods 42 can clamp and limit the charging gun 2, which can prevent the charging gun 2 from falling off accidentally, thus improving the safety of the charging station. Furthermore, the forward movement of the identifier 3 can better recognize the vehicle license plate, thereby improving the applicability of the charging pile.

[0036] Example 2

[0037] Based on Example 1, such as Figure 2 , Figure 7 and Figure 8 As shown, it also includes a shielding mechanism 6 for shielding the placement position of the charging gun 2. The shielding mechanism 6 includes a third guide rod 61, a shielding plate 62, and a third spring 63. Two third guide rods 61 are welded to the upper right part of the charging pile body 1. The two third guide rods 61 are arranged symmetrically front and back. The third guide rods 61 are located above the slide plate 52. The shielding plate 62 is slidably connected between the two third guide rods 61. The shielding plate 62 can shield the placement position of the charging gun 2. The third guide rods 61 can guide the shielding plate 62. Two third springs 63 are connected between the left side of the shielding plate 62 and the charging pile body 1. The third springs 63 are all wound around the third guide rods 61. The third springs 63 can make the shielding plate 62 move and reset.

[0038] When a vehicle is charging using the charging gun 2, to prevent people from accidentally putting their hands into the charging pile body 1, the position of the charging gun 2 needs to be blocked. Initially, the third spring 63 is in a compressed state, the cover plate 62 is in the leftmost position, and the charging gun 2 is in a state of holding the cover plate 62 in place. First, when the charging gun 2 is removed, the cover plate 62 is released. Then, under the action of the third spring 63, the cover plate 62 moves to the right, thus blocking the position of the charging gun 2 and preventing people from putting their hands into the charging pile body 1. Then, the vehicle can be charged. After charging is completed, the charging gun 2 is reset, and the charging gun 2 will push the cover plate 62 to move to the left and reset. At this time, the third spring 63 is compressed. Repeating the above operation, the cover plate 62 can block the position of the charging gun 2, thereby preventing people from putting their hands into the charging pile body 1 and improving people's safety.

[0039] like Figure 1 , Figure 2 , Figure 9 and Figure 10 As shown, it also includes a covering mechanism 7 for covering the identifier 3. The covering mechanism 7 includes a cover plate 71, a rotating rod 72, a torsion spring 73, and a fifth spring 74. The rotating rod 72 is rotatably connected to the middle of the front part of the charging pile body 1. The cover plate 71 is slidably connected to the lower part of the rotating rod 72. The cover plate 71 can cover the identifier 3. When the identifier 3 moves forward, it will contact the cover plate 71. Two fifth springs 74 are connected between the upper front side of the cover plate 71 and the lower rear side of the rotating rod 72. The two fifth springs 74 are arranged symmetrically on the left and right. The fifth springs 74 are both wound around the cover plate 71. The fifth springs 74 can make the cover plate 71 move and return to its original position. Torsion springs 73 are connected between the left and right sides of the rotating rod 72 and the charging pile body 1. The torsion springs 73 are both wound around the charging pile body 1. The torsion springs 73 can make the rotating rod 72 rotate and return to its original position.

[0040] Because the identifier 3 is easily damaged by wind and rain, it needs to be covered. First, when the identifier 3 moves forward, it pushes the cover plate 71 forward, compressing the fifth spring 74. Then, when the cover plate 71 reaches its foremost position, the continued forward movement of the identifier 3 compresses the cover plate 71, causing it to rotate upwards. This upward rotation of the cover plate 71 drives the rotating rod 72 to rotate, torturing the torsion spring 73. The identifier 3 can then smoothly move forward. Afterwards, the vehicle can be identified. When the vehicle is fully charged and the identifier 3 moves to the rear to reset, the rearward movement of the identifier 3 releases the cover 71. Then, the rotating rod 72 reverses under the action of the torsion spring 73, causing the cover 71 to rotate downward. Afterwards, the cover 71 moves to the rear to reset under the action of the fifth spring 74. The cover 71 can cover the identifier 3. Repeating the above operation, the identifier 3 can be covered by the cover 71, thereby preventing the identifier 3 from being damaged by wind and rain.

[0041] like Figure 1 and Figure 11 As shown, it also includes a guide mechanism 8 for positioning the cover plate 71. The guide mechanism 8 includes a fourth guide rod 81, an elastic rope 82, and a circular baffle 83. The fourth guide rod 81 is welded to the middle of the left and right sides of the front wall of the charging pile body 1. The cover plate 71 is slidably connected to the fourth guide rod 81. The elastic rope 82 is connected to the inner rear wall of the fourth guide rod 81. The circular baffle 83 is connected to the front side of the elastic rope 82. The circular baffle 83 can limit the cover plate 71 and is in contact with the fourth guide rod 81.

[0042] When the cover 71 needs to be rotated open, firstly, when the cover 71 moves forward and contacts the circular baffle 83, the upward rotation of the cover 71 will cause the circular baffle 83 to rotate. At this time, the elastic rope 82 deforms, and then the vehicle can be identified. After the vehicle identification is completed, and the cover 71 needs to be rotated downward to close, the circular baffle 83 is reset under the elastic force of the elastic rope 82. The reset of the circular baffle 83 can position the cover 71. Then the cover 71 passes through the fourth guide rod 81 again, which can better cover the cover. Repeating the above operation, the elastic rope 82 and the circular baffle 83 work together to guide and position the cover 71, thereby preventing the cover 71 from being inaccurate when it is reset.

[0043] like Figure 2 and Figure 12As shown, it also includes a starting mechanism 9 for activating the identifier 3. The starting mechanism 9 includes an L-shaped connecting plate 91, a slider 92, a fourth spring 93, and a start switch 94. The L-shaped connecting plate 91 is fixedly connected to the rear right side of the identifier 3. The slider 92 is slidably connected to the front right side of the charging pile body 1. When the L-shaped connecting plate 91 moves forward, it will contact the slider 92. The fourth spring 93 is connected between the right side of the slider 92 and the charging pile body 1. The fourth spring 93 can make the slider 92 move and reset. The start switch 94 is connected to the front right side of the charging pile body 1. The start switch 94 is electrically connected to the identifier 3. The start switch 94 can control the opening and closing of the identifier 3. When the slider 92 moves to the right, it will trigger the start switch 94 to open and close.

[0044] The identifier 3 needs to be turned off when not in use and turned on when in use. First, when the identifier 3 moves forward, it moves the L-shaped connecting plate 91 forward. The L-shaped connecting plate 91 moves forward and pushes the slider 92 to the right. At this time, the fourth spring 93 is compressed. The movement of the slider 92 to the right triggers the start switch 94, which enables the charging station to start and charge the vehicle. After the vehicle is charged, when the identifier 3 moves backward to reset, it moves the L-shaped connecting plate 91 backward, and then the slider 92 is released. Then, the slider 92 moves to the left to reset under the action of the fourth spring 93. The slider 92 separates from the start switch 94, and then the start switch 94 is turned off, which shuts down the charging station. Repeating the above operation, the start switch 94 can control the opening and closing of the identifier 3, thereby preventing the identifier 3 from being in the open state and wasting electricity.

[0045] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
